Generate a Random Number (New Number With Each Instance)

Hi there

I'm working on a process that creates two random numbers. The following ways have been tested already:

• I used the "Generate Data" operator and tried to use both the attributes as well the label
• I used the "Generate Attributes" rand()

I got to a positive result with each scenario. My result is showing me two numbers the way I want, alright. However, if I run the process a second time the numbers do not change (no random new number is generated) - the same numbers are the output of every new instance of the process.

What operator or work-around is to be used in order to get new random numbers for each time I run the process anew?

Many thanks in advance!
